Observation of plasmonic exceptional points
J. -H. Park, A. Ndao, W. Cai +5
Non-Hermitian singularities known as exceptional-points (EPs) have been shown to exhibit increased sensitivities but the observation of EPs has so far been limited to wavelength sc…
Integrated and Steerable Vortex Lasers using Bound States in Continuum
B. Bahari, F. Vallini, T. Lepetit +5
Orbital angular momentum is a fundamental degree of freedom of light that manifests itself even at the single photon level. The coherent generation and beaming of structured light…
Exceptional Points in three-dimensional Nanostructures
Ashok Kodigala, Thomas Lepetit, Boubacar Kanté
Exceptional points (EPs) are degeneracies in open wave systems where at least two energy levels and their corresponding eigenstates coalesce. We report evidence of the existence of…
Resonantly Trapped Bound State in the Continuum Laser
Thomas Lepetit, Qing Gu, Ashok Kodigala +3
Cavities play a fundamental role in wave phenomena from quantum mechanics to electromagnetism and dictate the spatiotemporal physics of lasers. In general, they are constructed by…
Extremely Thin Dielectric Metasurface for Carpet Cloaking
LiYi Hsu, Thomas Lepetit, Boubacar Kanté
We demonstrate a novel and simple approach to cloaking a scatterer on a ground plane. We use an extremely thin dielectric metasurface (λ/12) to reshape the wavefronts distorted by…
